Breast Cancer
As of October 8, 2024, the Ontario Breast Screening Program (OBSP) has updated its guidelines to enhance early detection of breast cancer. Individuals aged 40 to 74 are now eligible for routine mammography screening. For those aged 40 to 49, it's recommended to discuss the benefits and potential risks of screening with a healthcare provider to make an informed decision. Generally, individuals aged 50 to 74 are advised to undergo mammograms every two years. Cancer Care Ontario

Regular screening is crucial for early detection and effective treatment of breast cancer. If you're within the eligible age range, consider scheduling your mammogram to maintain your breast health.
Colon Cancer
In Ontario, colorectal cancer screening is recommended for adults aged 50 to 74 who are at average risk, meaning they have no personal or family history of colorectal cancer, inflammatory bowel disease, or high-risk genetic conditions. The main screening tool for this group is the Fecal Immunochemical Test (FIT), which should be done every two years. The FIT is a simple, at-home stool test that detects hidden blood, which can be an early sign of colorectal cancer.
If a Fecal Immunochemical Test (FIT) result is positive, it means that hidden blood was detected in the stool sample. While this does not necessarily indicate cancer, it does mean that further investigation is needed to determine the cause of the bleeding.
The next step after a positive FIT is typically a colonoscopy. During this procedure, a doctor examines the inside of the colon using a flexible tube with a camera. A colonoscopy allows for a close look at the lining of the colon and can detect any abnormalities, such as polyps or cancerous growths. If polyps are found, they can often be removed during the procedure, which may help prevent cancer from developing in the future.
It is important for patients to follow up with their healthcare provider promptly after a positive FIT result to schedule the colonoscopy. Timely follow-up is essential, as it helps in identifying any potential issues early, which can significantly improve treatment options and outcomes.
For those with a family history of colorectal cancer in a first-degree relative (parent, sibling, or child), screening is recommended to start at age 50 or ten years before the age at which the relative was diagnosed, whichever comes first. These individuals may be advised to undergo colonoscopy rather than the FIT, as it provides a more thorough examination of the colon.
The goal of these screening guidelines is to detect colorectal cancer early, when it is more treatable, or to find and remove precancerous polyps to prevent cancer from developing.
Cervical Cancer
Cervical cancer screening in Ontario is an essential preventive measure for women, aiming to detect early changes in cervical cells before they develop into cancer. The screening is done through a Pap test, which collects cells from the cervix and is recommended for most women starting at age 25. For women aged 25-69, a Pap test is advised every three years, as long as prior results are normal. Women over 70 can stop screening if they have had three or more normal tests in the previous ten years.
Regular cervical cancer screening is crucial because it helps detect abnormalities early, allowing for timely intervention. The Pap test can identify both precancerous changes and early stages of cervical cancer, when treatment is most effective. Screening is particularly important for women who are or have been sexually active, as HPV (human papillomavirus), a common sexually transmitted infection, is a primary cause of cervical cancer. Ontario offers the HPV vaccine, which further reduces the risk, but even vaccinated individuals should continue regular screening.
Prostate Cancer
Prostate-specific antigen (PSA) screening is a blood test used to detect prostate cancer in its early stages. While PSA screening can benefit some individuals by identifying cancer before symptoms appear, it also has limitations that are important to understand. PSA levels naturally increase with age, and thresholds are adjusted accordingly: generally, levels over 2.5 ng/mL may prompt further investigation in men under 50, while levels over 4.0 ng/mL may be considered high in men over 60.
However, elevated PSA does not always indicate cancer. Conditions such as benign prostatic hyperplasia (BPH), prostatitis, urinary tract infections, or recent ejaculation can also raise PSA levels. This can lead to false positives, resulting in unnecessary anxiety, repeat testing, and even biopsies, which may have their own risks. Additionally, PSA screening may detect slow-growing cancers that might not cause harm within a man's natural lifespan, leading to overtreatment and potential side effects, such as incontinence or erectile dysfunction.
Given these factors, the decision to undergo PSA screening should be an informed one, tailored to each individual's age, risk factors, and overall health. Primary care providers in Ontario can help patients weigh the potential benefits of early detection against the possibility of unnecessary interventions, supporting patients in making choices that align with their health priorities.
